The Ultimate Guide to Smart Home Locks : The who, The what and the why

Smart home technology is no longer just about lights and thermostats—it’s now transforming one of the most essential parts of home security: door locks. A smart lock not only secures your home but also adds convenience, control, and peace of mind. However, with so many types and features available, choosing the right one can feel overwhelming. Understanding the different types of smart locks and the certifications that guarantee their reliability will help you make the best choice.

Types of Smart Home Locks

1. Keypad & PIN Code Locks

These locks replace or integrate with traditional deadbolts, allowing you to enter your home using a code.

• Pros: No need for physical keys, customizable codes for guests, backup key option.

• Cons: PINs can be forgotten or shared too widely.

Best for: Families, rental properties, and households that frequently host guests.

2. Smartphone App-Controlled Locks

These locks connect to your smartphone through Bluetooth or Wi-Fi. They can lock/unlock with a tap, send alerts, and allow remote access.

• Pros: Remote management, activity tracking, integration with smart home systems.

• Cons: Dependent on internet or Bluetooth range; battery power needed.

Best for: Tech-savvy homeowners who want complete control from anywhere.

3. Biometric (Fingerprint) Locks

These use fingerprint scanning for access. Some models also combine biometrics with PIN codes or smartphone control.

• Pros: High security, no need to remember codes or carry keys, fast entry.

• Cons: More expensive, may have issues with dirty or wet fingers.

Best for: Security-conscious homeowners who want fast, keyless entry.

4. Key Fob / RFID Locks

These locks work with a fob, card, or tag you tap against the lock to gain access.

• Pros: Quick and easy entry, no codes to remember.

• Cons: Fobs can be lost or stolen, usually less common in residential homes.

Best for: Small businesses, apartments, or homes with children who may not remember PINs.

5. Hybrid Smart Locks

These combine multiple methods: PIN, smartphone app, biometric, or mechanical key backup.

• Pros: Maximum flexibility, multiple ways to unlock, great for mixed households.

• Cons: Higher cost, more complex setup.

Best for: Households that want multiple backup options and extra convenience.

Important Certifications for Smart Locks

When shopping for a smart lock, certifications matter. They indicate the safety, durability, and compatibility of your lock. Here are the most common ones to look for:

1. ANSI/BHMA Ratings

The American National Standards Institute (ANSI) and the Builders Hardware Manufacturers Association (BHMA) grade locks on durability and security:

• Grade 1: Highest residential security (most durable, commercial-level protection).

• Grade 2: Mid-range (common in quality residential locks).

• Grade 3: Basic protection (minimum standard).

For smart locks, aim for Grade 1 or 2 for best protection.

2. UL Certification (Underwriters Laboratories)

This ensures the lock has been tested for fire resistance, safety, and durability. UL-certified smart locks meet strict safety standards, which is especially important for insurance and peace of mind.

3. Z-Wave & Zigbee Certification

If you want your lock to integrate with other smart home devices (like Alexa, SmartThings, or Hubitat), look for Z-Wave or Zigbee certifications. These ensure compatibility with wider smart ecosystems.

4. Wi-Fi Alliance Certification

For Wi-Fi-based locks, this certification ensures secure, reliable wireless communication. It reduces risks of hacking and connection failures.

5. Matter Compatibility

Matter is the new universal smart home standard, backed by Apple, Google, Amazon, and others. A Matter-certified lock ensures cross-platform compatibility, meaning you can control your lock with any major smart home system.

6. Energy Star / Battery Efficiency Standards

While not always visible, some locks undergo efficiency testing to ensure longer battery life and power optimization—important since most smart locks run on AA or rechargeable batteries.

Final Thoughts

Smart locks offer far more than just convenience—they’re a critical layer of modern home security. Whether you prefer the simplicity of a PIN code, the high-tech biometric scanner, or the flexibility of a hybrid lock, knowing what certifications to look for ensures you’re investing in a safe, durable, and future-proof solution.

When shopping, always check for:

• ANSI/BHMA Grade 1 or 2

• UL safety testing

• Smart home compatibility certifications (Z-Wave, Zigbee, Matter, Wi-Fi Alliance)

By pairing the right type of lock with the right certifications, you’ll have a smart lock that not only secures your home but also integrates seamlessly with your lifestyle.
